Abstract: Barcode readers and methods for directing fields-of-view of imaging sensors of barcode readers are disclosed herein. An example barcode reader includes a housing, an imaging sensor positioned within the housing, and a transflective mirror positioned within the housing and in a path of a field-of-view of the imaging sensor.

Abstract: A workstation processes a product by imaging an indicium associated with the product in a transaction, and images a sheet-like target associated with the transaction. A window is supported in a window plane in contact with the target during target imaging. An imaging assembly captures light from the indicia during product processing, and from the target during target imaging, over a plurality of fields of view extending along different directions through the window. Each field bounds an area in the window plane that is smaller than the entire target. At least one pair of the fields partially overlaps each other in the window plane. The fields overlap contiguous portions of the target during target imaging. The light from the contiguous portions is captured by the imaging assembly as a plurality of target images. A controller compiles the target images into a single output image indicative of the target.

Abstract: An arrangement for, and a method of, electro-optically reading a target by image capture, employ an aiming assembly for projecting an aiming light pattern on the target that is located within a range of working distances relative to a housing, an imaging assembly for capturing an image of the target and of the aiming light pattern over a field of view, and a controller for determining a distance of the target relative to the housing based on a position of the aiming light pattern in the captured image, for determining a scanning resolution based on the determined distance, for comparing the determined scanning resolution with a scanning resolution setting, and for processing the captured image based on the comparison.

Abstract: A method includes transmitting from at least one of the imaging sensors to a controller a short frame data that is collected by the at least one of the imaging sensors when the illumination source is activated to provide the illumination light toward the target object with a first illumination level. The method further includes transmitting subsequently from the at least one of the imaging sensors to the controller a regular frame data that is collected by the at least one of the imaging sensors when the illumination source is activated to provide the illumination light toward the target object with a second illumination level that is determined based upon the short frame data. The size of the regular frame data being at least 50 times larger than the size of the short frame data.

Abstract: An imaging system for electro-optically reading a symbol located within a range of working distances from the system, utilizes a solid-state imager for capturing return light from the symbol and for generating an electrical signal indicative of the captured return light, and a controller for decoding the electrical signal into data indicative of the symbol A memory stores a known set of values for a plurality of optical characteristics of the symbol, such as size and contrast characteristics of the symbol when the symbol lies in a restricted zone within the range of working distances. The controller is operative, after the symbol has been successfully decoded, for processing the size and contrast characteristics of the decoded symbol, and for determining that the decoded symbol has been successfully read within the restricted zone when each size and contrast characteristic lies within the known set of values stored by the memory.

Abstract: An arrangement for, and a method of, preventing a misread of a one-dimensional symbol that can be read in either one of two polarities in an electro-optical reader. A data capture assembly captures light from the symbol, and generates an electrical signal indicative of the captured light. A controller simultaneously processes and decodes the electrical signal as a first decoded result of one of the polarities and as a second decoded result of the other of the polarities. The controller also determines the validity of the first and second decoded results, and generates an output in dependence upon the validity determination.

Abstract: An apparatus and method electro-optically read indicia, such as a direct part marking (DPM) code, that is raised or sunken relative to a target surface on a target. A solid-state, distance imaging sensor captures a target image comprised of a first set of pixels having first distance values that correspond to a first distance of the code from the sensor, and a second set of pixels having second distance values that correspond to a second distance of the target surface from the sensor. A controller reads the indicia by distinguishing between the first set of pixels and the second set of pixels within the image, by determining abrupt changes in the distance values among neighboring pixels.

A workstation microprocessor processes the target data during an active mode, and stands by during a standby mode. An accessory microprocessor acquires the additional target data, and sends the acquired additional target data to the workstation microprocessor for processing during the standby mode.
